Socket head cap screw DIN 912 / ISO 4762, hex socket AF 4, M 5x20, steel plain (black) 8.8

Where the screw head has to disappear flush into a counterbore, this DIN 912 socket head cap screw works with M 5 and 20 mm length. Head diameter 8.5 mm and head height 5.0 mm define the counterbore, and the tool engages in the AF 4 hex socket. The material is steel plain (black) 8.8.

• Property class 8.8 in plain finish for protected or oily installation points.
• Head diameter 8.5 mm at 5.0 mm head height to DIN 912, matching a cylindrical counterbore.
• The AF 4 hex socket transmits the tightening torque without wrench flats on the head.
